Secret Puck (Campus Nights #1) by Rebecca Jenshak

Secretly hooking up with the team captain's sister was a bad idea.
In my defense, the first time I saw her I didn't know who she was.
Kind, gorgeous, a little naïve. Ginny brightened my world from day one.
I knew I was no good for her. She was just out of a relationship and I had a reputation for having a new girl in my bed every weekend.
I tried to do the right thing. Honest.
I'm the one who insisted we should be just friends.
That lasted about as long as you'd expect.
But Ginny? She's the best - best friend, best everything.
So yeah, hooking up with the team captain's sister wasn't a great idea.
Would I do it again?
In a heartbeat.
